STRAIGHT-KNITTING FRAME.

Application filed November 13, 1924, Serial No. 749,646, and in GermanyDecember 18, 1923.

My invention relates to straight knitting frames and has particularreference to such a frame provided with a movable knockover comb theknock-over sinkers of which are-provided with a locking-in throat.

The known knock-over sinkers provided with a locking'in throat are movedelther in a horizontal and vertical direction only or, if the knock-oversinkers are rotatable,

the pivot point is not arranged in such a manner, that, by simplyturning the knockover sinkers, the loops may be transferred from thejack sinkers directly to the knockover sinkers provided with alocklng-in throat.

The object of the present invention is to provide means which allow thisdirect transfer of loops for which purpose the knockover sinkers arepivotally arranged about an axis passing through the points of theirnibs.

In the accompanying drawings the invention is illustrateddiagrammatically by way of example. Figs. 1 and 2 are two views of thedevice according to the invent-ion showing the parts in two differentpositions.

Figs. 37 are detail views of the knock-over comb and the jack sinkers indifferent working positions.

The knock-over sinkers 1, provided with a locking-in throat 1, a nib 1and a beak 1 are arranged in a horizontal bar 2 which is pivoted to theends of arms 3 of double armed levers 3, 9 mounted upon a shaft 4-.

The pivot axis of the bar 2 around the arms 3 is arranged in the sameaxis as the points of the nibs 1 of the locking-1n throats 1 of theknock-over sinkers 1.

Mounted upon a shaft 5 journaled in the machine frame is a disc 8carrying cams 6 and 7. The free end of the arm 9 of the double-armedlever 3, 9 carries a roller 9 bearing against the disc 8. Upon a secondshaft 10 a bell crank lever 11, 12 is arranged the arm 11 of which alsocarries a roller 11 bearing against the disc 8. Pivoted to the other arm12 of the bell crank lever 11, 12 is a rod 13 the free end of which isconnected to an arm 14 pivoted to the axis of the bar 2. The jack sinkeris designated 15 and 16 is the needle.

Normally the parts are in the position shown in Fig. 1 in which therollers 9 and 11 carried by the arms 9 and 11 bear against the circularpart of the disc 8. The knockover sinker 1 assumes the position shown inFig. 3 in which by advancing of the jack sinker 15 the sinking of theloops begins. 4 shows the pressing off, following the slnking of'theloops. Thereupon the cam 6 engages the roller 11 on the arm 11 which isshifted. Hereby the arm 12 and by means of the rod 13 the arm 14connected to the bar 2 is lifted. The knock-over sinker 1 thereby comeinto the position shown in Figs. 2 and 5. As in this movement theknock-over sinkers 1 turn about the point of the nib 1 of the locking-inthroat 1, the knock-over point of the knock-over sinker 1 approaches thejack sinker 15 in such a manner, that the loop, without making a specialway, is directly and safely taken over from the knock-over sinker 1.Fig. 6 shows the knocking-over proper, whereas Fig. 1 illustrates thelocking-in.

What I claim is:

1. In a straight knitting frame, the comblnation of knock-over sinkerseach provided with a locking-in throat, a nib and a beak, withjack-sinkers, a bar carrying the knockover sinkers and means for turningsaid bar parallelly to itself in such a direction that the beak of eachknock-over sinker approaches the loop-carrying end of the appertainingjack-sinker, the points of fulcrum of said bar being situated in theideal line passing through the ends of the nibs of the said knock-oversinkers, as set forth.

2. In a straight knitting frame, in combination jack sinkers, knock-oversinkers having each a locking-in throat, a nib above the latter, and abeak below the same, a bar carrying these knock-over sinkers,doublearmed levers carrying this bar at one of their arms, the points offulcrum of these levers lying in the ideal line extending through theends of the nibs of the said knock-over sinkers, and means engaging saiddouble-armed levers at their other arms and rocking them inpredetermined intervals, as set forth.

3. In a straight knitting frame, in combination jack sinkers, knock-oversinkers having each a locking-in throat, a nib above this latter, and abeak below the same, a bar carrying these knock-over sinkers,double-armed levers carrying this bar at one of their arms, the pointsof fulcrum of these levers lying in the ideal line extending through theends of the nibs of the said knock-over sinkers, a shaft and a camthereon, a lever rocked by this cam in predetermined intervals, armsconnected with this lever, and rods connecting these arms with the freearms of said double-armed levers, as set forth.

4. In a straight knitting frame, in combination jack sinkers, knock-oversinker-s having each a locking-in throat, a nib above this latter, and abeak below the same, a bar carrying these knock-over sinkers,double-armed levers carrying this bar at one of their arms, otherdouble-armed levers supporting the first-mentioned ones at their upperends, the points of fulcrum lying in the ideal line extending throughthe extreme ends of the nibs of the knock-over sinkers, a shaft and twocams thereon, a lever arranged to be rocked by one of the cams inpredetermined intervals, arms connected with this lever, and rodsconnecting these arms With the free arms of the first-mentioneddouble-armed levers, the second cam being arranged to rock thedouble-armed lever mentioned in the second place in predeterminedintervals, substantially as de scribed.

In testimony whereof I aflix my signature.
